AZN's Jeeper Sleeper

The purpose of this post is to be as technical as possible about Jeeper Sleeper and answer some of the most common questions that have come in after airing the Daily Driver episode on Street Outlaws and making an appearance at South Carolina Motorplex for No Prep Kings airing soon! Farmtruck and myself always try to be as transparent as possible with our builds so that no one feels as though we're hiding information or trying to mislead anyone.  Thanks for your support as always and there's much more to come from this build by Modern Muscle Xtreme. 

Modern Muscle Performance / owner Dave and Stephen the GM were manning our booth during PRI 2016 when AZN happened to be wondering by and saw our “Grouch” Jeep SRT8 build. He imediately stopped and began to look over the build quality and talk to Stephen and Dave about what went into the project. After some discussion AZN made it known to us that he had just purchased a 2008 Jeep SRT8 Grand Cherokee and would love to do something with it similar to what we had done with the Grouch, but money was an issue with that large of a build. She still has heated seats and A/C!

Dave and Stephen took the opportunity to work together with AZN and certain manufacturers to make his #JEEPERsleeper build happen. Starting with a 6.1L based “405” HEMI stroker engine and additional modifications to get this monster down the 1/4 mile with the quickness.
